France
Hong Kong
French founders, among the most heavily taxed in Europe, keep asking the same question: can a Hong Kong company legally lower my tax? Here is the honest, two-sided answer. Owning a Hong Kong company is legal, and Hong Kong is genuinely low-tax. But whether that low tax reaches you is decided by French rules, not by Hong Kong. Run the company from your living room in France, and French anti-avoidance rules pull the saving straight back.
This guide gives you the real 2026 picture: what Hong Kong offers, how articles 209 B and 123 bis actually work (with the thresholds the sales pages get wrong), and the specific conditions under which a Hong Kong company is legitimate planning rather than exposure.
This is general information, not tax advice, and it is a sensitive tax and legal topic. French cross-border tax is complex and enforced. Have any structure reviewed by a qualified advisor before acting.
What Hong Kong genuinely offers
- Low, territorial profits tax: 8.25% on the first HK$2M, 16.5% above, and often nothing on genuinely offshore profits.
- 100% foreign ownership, set up remotely from France.
- No VAT, no capital gains tax, no dividend withholding at the Hong Kong level.
- A credible, bankable entity for international business.
The appeal is real. The question is whether France lets you keep the benefit while you remain French-resident.
Can a French resident own a Hong Kong company?
Yes. Ownership is not the issue. A French resident can legally own and direct a Hong Kong company. The issue is how France taxes the arrangement, which is where most "0% tax" pitches fall apart. France has two CFC rules, one for companies and one for individuals, plus a residency doctrine.
French rule 1: CFC for companies (article 209 B)
If a French company holds, directly or indirectly, more than 50% of a foreign entity that benefits from a "privileged tax regime," France can tax that entity's profits in France. For a non-EU entity like Hong Kong, the escape clause is not automatic: the taxpayer must prove the structure has a real economic purpose and effect beyond locating profit in a low-tax place (genuine industrial or commercial activity). Without that proof, the profits are taxed in France despite Hong Kong's low rate.
French rule 2: CFC for individuals (article 123 bis)
This is the one that catches solo founders, and most pages omit it. If a French-resident individual holds 10% or more of a foreign entity under a privileged regime whose assets are principally financial or monetary, France taxes that entity's income in the individual's hands.
The key nuance to understand:
- Passive / holding Hong Kong companies (mainly financial assets, interest, dividends, royalties) are squarely in 123 bis territory.
- A genuinely active trading Hong Kong company can fall outside the "principally financial" test, so the analysis is not automatic. Substance and the nature of the income decide it.
The low-tax trigger (article 238 A): it is not "half" anymore
Here is the factual correction that matters most, because nearly every French-language incorporation page still repeats the old rule. A foreign regime counts as "privileged" when its profit tax is 40% or more lower than the French tax that would be due (article 238 A). This is not the old "less than 50%" test; it was broadened by the anti-fraud law of 23 October 2018 (loi n° 2018-898), in force from 1 January 2020.
In practice, against a French corporate rate of roughly 25%, a foreign regime is "privileged" once its effective tax falls below about 15%, which Hong Kong's territorial or offshore treatment (often 0%) easily triggers. So assume the trigger is met and focus on substance, not on hoping the rate is "high enough."
Effective management and residence
Separately from CFC, if the Hong Kong company's real decisions are taken in France (because you, the decision-maker, live and work there), France can treat the company as having its effective management (and a permanent establishment) in France, and tax it accordingly. One reassuring point: Hong Kong is not on France's list of non-cooperative states (ETNC), so the harshest irrebuttable presumptions do not apply. The substance burden, however, stays on you.
The line: legal optimization vs evasion
State it plainly, because this is YMYL. The saving is real only with genuine substance plus real relocation of management, or a genuinely active, staffed Hong Kong operation. A letterbox Hong Kong company controlled and managed from France, claimed as 0%, is not "optimization." It is the exact fact pattern that 209 B, 123 bis, and the effective-management doctrine are written to catch, with reassessment and penalties. We help build the compliant version, or tell you honestly that it does not apply to your situation.
When a Hong Kong company legally helps, and when it does not
| It can be legitimate when... | It does not work when... |
|---|---|
| You genuinely relocate and change your own French tax residency | You keep living in France and run the company from there |
| The company has real substance and active operations | It is a passive shell booking profits offshore on paper |
| It runs genuine active trading, potentially outside 123 bis | It mainly holds financial assets (squarely in 123 bis) |
| Decisions are genuinely taken outside France | Day-to-day management sits at your French desk |
The honest summary: a Hong Kong company is a legitimate tool when the structure reflects reality, especially if you move, not just the company.
The remote setup path
If a Hong Kong company genuinely fits your situation, setup from France is quick: name check, certify KYC, sign electronically, file with the Companies Registry (about one working day), secretary and registered office appointed, then banking. The full walk-through is in how to register a Hong Kong company, and banking is in opening a business bank account. The generic two-sided tax logic sits in Hong Kong tax for non-residents.
The bottom line, and how CorpSec helps
For a French resident, a Hong Kong company is a genuine tool in the right situation and a costly mistake in the wrong one, and the deciding factors are French: 209 B, 123 bis, the 238 A trigger, and where the company is really managed. That is not a call to make from a blog or a "2-day, 0% tax" sales page.
This is where CorpSec fits. We set up the Hong Kong company end to end and give you an honest read of your French position first, so you know whether it actually helps before you commit, and we point you to a qualified French advisor for the parts that need one. No promised rate, just the real trade-offs.
Frequently asked questions
Can a French resident legally own a Hong Kong company?
Yes, ownership is legal. What matters is how France taxes it: through CFC rules (209 B for companies, 123 bis for individuals) and the effective-management doctrine, which can bring the profits into French tax.
Will a Hong Kong company make me tax-free in France?
No, not while you remain French-resident and manage it from France. The CFC rules and the effective-management doctrine can tax the profits regardless of Hong Kong's rate.
Is the French low-tax threshold still "less than 50%"?
No. Since 1 January 2020 (under the anti-fraud law of 23 October 2018), article 238 A treats a regime as privileged when its tax is 40% or more lower than the French tax due, so against a ~25% rate the trigger bites once the effective foreign tax is below roughly 15%. Hong Kong easily meets it.
Does article 123 bis apply to my one-person Hong Kong company?
It applies to a French individual holding 10% or more of a foreign entity whose assets are principally financial. A passive holding is caught; a genuinely active trading company may fall outside the test, depending on substance.
When does a Hong Kong company actually reduce tax for a French founder?
Mainly when you genuinely relocate and change your own tax residency, or when there is real active substance in Hong Kong. Paper structures run from France do not work.
Is this legal optimization or evasion?
Genuine relocation and real substance are legal planning. Hiding a French-run business behind a Hong Kong label is evasion. Always get advice.
